PoULTRY-SPRAYING APPARATUS.

Application filed February 14, 1922.` Serial No. 536,557;

poultry 'spray-.-

minating lice or other harmful insects. Thisy is usually carried out by spraying the poultry with a liquidor powder serving tor carry a poison effective against lice orfthe like.

Vith the above in Iview it. is the objecty ofthe present invention to provide an apparatus whereby poultry may be` sprayed with a liquid orpowder for destroying lice or the like in a highly efficient manner.

It is also an object of the inventionv that the apparatus be adapted to bef associated with a poultry house in such a'manner that during the entrance or exit of poultry from the house the same will bey eii'iciently sprayed in an automatic manner and withoutany attention or care on the part ofianattendant.

It is also an object of the invention that the spraying apparatusl be extremely simple in construction and not subject to getting` out of order. f

Other objects andobjects relating to details ofl construction, combination and arLk rangement of parts will hereinafter appear in the detailed description to follow."

Figure l is an enlarged perspective view illustrating the application of the invention,

Figure 2 is a rear elevation ofthe spraying apparatus when fully assembled,

Figure 3 is a side elevationof thesame, and

Figure 4 is a detailed view illustrating the electrical connections for the electromagnet Referring to the drawing more 'particu-A larly, H indicates generally a poultry housing, the rear wall of vwhichhasbeen broken away in orderto show inelevati'on anvinside side wall thereof, in which wall there isfan entrance or runway for poultry to gointo and out of said housing. y j

In carrying out the present invention, I provide a box B which isopen at eachof its ends which may be ofk any desirable shape and dimension and having two opposing walls removed so that` poultry may pass through the box. The box B rshould be positioned within the poultry yhousing sci.

that one of its open walls is in register with Figure l. To the bottom of the boxrB there the entrance yto the chicken house as at 10,

is hinged as at 11 a platform P, and near the inner end of the platform thereis 'posi` tioned beneath'the'same alspring i'ngeri12 which `is adapted to yieldingly uphold-the position las best zillu'ssame in an inclinedtrated in FigurefB;

The spring 12 should be adapted so that comes upon theplatform the samev Willjbe depressed. 1 v

y when a fowl rsuch as a chicken or the like` Also, there isproviaea a amr rwhch is secured to one side wall of the box B .which has projecting thereina pipe 13.said pipe terminating pat its i lower end adjacentr the lower end of the'tank T, as .shown in kFigure r2of the drawings, and communicating atits upper end with anvalve V. The pipe 13 T throughits lower end and also through thef'opening 13adjacent its upper end, the purpose of whichl rwill be, later explained. The valve V `may beiofl any suitable known 8U communicates with the. interior of the tank n type of construction and having an operatv ing handle 14 adapted to be moved for opening and closing said. valve. Connected with the operating handle 114 is a coil spring 15 adapted to normally hold the valve handle so thatthe valve Vis closed with respect to the pipefl. Mountedupon the saine side wall of'thebox B isan electro-magnet M which has aeplunger 16 associated therewith, said plungerbeing'pivotally yconnected at` its lower end as at "to the valve operating handle 14. The magnet M should be of such construction 'i that `when `the sanne is energized it will move the* plunger 16 upwardly for operating thevalve V', that is, opening the valve with respeot'to the pipe 13.

, Extending from'the'magnet M is a suitable conduit as r at 18"'through which there passes electric current supplywires 19 and y20for said magnet. y`At21 there is provided a junction box in which? the wire '19 is divided kand provided *withl agpair of contoy a kpredetermined position bythe' weight of a fowl uponthe platform I). The wires 19 and 2O are further extended toa suitable source of elctric current supply which will later be referred to.

instance, being arranged in a substantiallyY verticalplane,v as shown, and each being provided with a plurality of spray nozzles 30. `Preferably each pipe carries a spray nozzle 30 at each end thereof and also a spray nozzle is positioned centrally Ywith and f conditions.

respect to the end nozzles. It is to be un-v derstood that any number of nozzles B may be used depending upon requirements The nozzles point inwardly with respect to the poultry house H.

Communicating with the valve V is a pipe "32 which in turn is connected -at its other end to a hose or the like 33, said' hose communicating' at its opposite end with the Jtank with a compressed air reservoir R thro-ugh the valve 34. The purpose of the air reservoir Ra is to supply compressed air to the tank T at a certain pressure. Any suitable means/may be utilized for supplying the` reservoir R with compressed airv at a predetermined value. In' the presentinstance, I have shown an air compressor A which is driven by an electric'motor E by the means of a beltl. A belt tightH ening means 36 may also beernployedl The air reservoir R- may also have a gauge G and a release valve V. For supplying the motor E-with electric current a suitable switch board may be used as at S, which f. may be supplied from anyV desirablesource yQrrelectric current and whichfmay carry a' switch r37 adapted tobe operated tov drive thef'mo-tor E at the required intervals for maintaining the pressure within the reservoirl't` at a predetermined degree.` Also the switch board S4 may be utilized. for supplying the wires 19Jand- 20% for operating thecelectro-magnetM by extending a suitable cablei or wires as.v shown i from ,the switch board vS -Y to connect with the `wires 19 and,20,.-Fignre l; i r

In thefoperationY of thepresent apparatus, theftanlr-T is 'filled with a liquidpo-ison or a powder poison for destroying poultry lice, and then thegswitch board Sis properly connected with an electric` source of sup-' ply. The' bonT Bris; arranged, as; shown in Figure l. llfhen the lfowl enters the door or runway l0 and rsteps upon-the platform P, the inner end of said platform tilts downwardly against the tension spring 12 and causes the contact linger 23 to establish an electric circuit to the electro-magnet M. The electro-magnet M upon being energized lifts the plunger 16 and opens the valve V. Upon opening the valve V compressed air is permitted to enter the tank T through pipel. Air passes from the pipe 13' through its lower end and open ing 13. If the tank T has powder therein, the air entering from. the lower end of tank .lifts the powder and the air entering from the opening 13 forces it to pass through the pipe 24 and to the nozzles 30. By this` arrangement the powder is kept in circulation and has nochance to clog or pack. If Vliquid poison is used'theair entering through the opening` 18 of pipe 13. atomizes the liquid forcedfrom the tank and causes a fine spray to issuefrom the nozzles 30.

Also it may be mentioned that the arcuate shaped pipe portion 29 should be.' sov arranged that the spray issuing from the nozzles 30' will be directed inwardly withr relation to the poultry house. By this arrangement, the spray strikes the fowl atthe'lrear andefticiently sprays beneath the feathers thereof... Upon `the fowl passing off the platform P the platform returns to its original position, asA shown in the different Figures, and the circuitv through the electro-magnet vM is opened and the valve V closed with relation to the pipe 13.

It lmay be herev mentioned that by'eX- periment'it has been foundv that with anl apparatus of the character heretofore described, the operation for spraying afowl will .be carried on in a noiseless manner and with the result that the fowl being treated is at no time scared and they .will

a passageway, a tiltable platform forming the bottom or floor of said passageway,` a

pairy of contact membersy disposed beneath the platform, a bridging member forV said contacts carried by the platform and adapt# ed to connect the same when" said platform is tilted in avpredetermin'ed direction, an electricalxcircuit adapted to be closed with thel connecting of said contacts, and-means pass through the box B without hesitancye f connected With said electrical circuit adapted' to force a liquid through said nozzles when said oircuit'is` closed.

2. ln an apparatus of the character described, a tiltable platform, a pair of spray nozzles one positioned upon each side of the platform and opposing each other, a liquid tank communicating With each spray nozzle, a valve controlled pipe connected to a source of compressed/air supply and extending into said tank, the free end of said pipe being open and in close spaced relation with the bottom of the tank, and

ing to furtherestablish communication with the interior of the tank and thereby toy atomize liquid Within the tank When com-*V pressed air is admitted to the tank through said pipe, and electrical means whereby upon the platform being tilted the valvecontrolled pipe Will be open topermit compressed air to enter said liquid tank and thereby to atomize said liquid and force the same in an atomized state through said spray nozzles.
